From the top of my head, I'd say display lag, EVF lag, depends also on the viewed subject. A rapid change of lighting, colours, will affect how fast a pixel reaches the new state, along with other effects like ghosting if motion is involved,....

 

Also, it seems it will depend on the used technology too and that OLED are theoretically much faster 0.01ms vs typical 1-16ms for LCD technology (IPS, TN,...). Then, there is input lag, caused by the system before the panel circuitry and probably a few other parameters, and then shutter lag, ...

 

I'd guess it's going to be round 30ms all in all :-P for the EVF only? Just a totally wild guess.

 

But I'm not sure it's a "new problem" to look at while shutter lag are still in tens of milliseconds ? I mean, you're still going to need "sensing/planning" ahead of pressing the shutter.

Quick SLRs have about 50 ms of a shutter lag - and electronic first shuttered cams can be substantially faster than this e.g. Fuji X100s is 11ms according to IR. So your guessed finder lag figures are in the same magnitude. Though I would not be surprised if an oldish E-P1 hat way mor than this.


But you are right - for practical purposes one has to add the two.
